Micro guitar amp head. The Jackman Bantamp head blends valve and solid state guitar amplifier technology, resulting in a tiny amp head that can produce an immense sound representative of a classic British amp. The Jackman has a 1 x 12AX7 preamp tube - The ability to reproduce the true sound of your guitar was a key factor in assessing a tube for use with the JOYO Bantamp series. The 12AX7 pre amp tube produces the warm smooth overdrive tones that do not clip tone as a typical fixed state amp head would. With 2 channels flick the Jackman amp to the clean channel and use with your array of guitar pedals. A two channel amp makes a guitar head twice as versatile as alternatives and a makes great companion for musicians at practice or on the road. The Jackman comes alive with its gain settings, you may want to use your favourite overdrive pedals to push it even further into higher gain territory with your own unique flavour. The FX loop on a guitar amplifier enables you to put your modulated based effects (Phasers, Flanger, tremolo and Chorus) after the Jackman delivers its drive magic. The FX loop keeps the modulated effects pure and will prevent them from becoming muddied from the amp gain. Pair your Bluetooth device to the Jackman and jam along to your favourite classic rock tracks, connect your external device via Bluetooth and play your audio tracks cleanly through the amps Bluetooth receiver channel. Headphone out with built in cab speaker amp simulation. The amp has a speaker out rated at 8 Ohm and can also be operated at 16 Ohm.
